Once again the new quality St (formaldehyde-free) microcapsule may be used, as it has the advantage of behaving very much like the classic melamine-formol microcapsules and uses the same ligands. This may be ideal for clients used to using melamine microcapsules but who want to eliminate formaldehyde, an increasingly problematic ingredient.

Applications

A few of the applications developed by MCT are listed below. Some are in their early stages and others have been widely marketed for some time now.

The main markets involved are:

Cosmetics
Cosmetotextiles
Paper and non-woven
Graphic arts
Odor maskers and deodorants
Food products
Detergence - Phytosanitary products

MICROCAPSULES FOR THE COSMETICS INDUSTRY

The Microsil® microcapsules, with their shell made of silicone copolymers, were specifically designed for this industry.
All of the tests performed by a well-known laboratory in its hardest-to-use form (cationic microcapsules containing a caffeine organic solution) show excellent skin acceptance and flawless toxicology so that these microcapsules can be considered to be hypoallergenic.

They can have an anionic (Type s and IS) or cationic (Type SK and ISK) charge
In their dry form, they can easily be admixed to makeup formulations.

Lipophilic actives:

UV Filters
Retinol
Oils of borage seed, shea butter, aloe-vera, etc…
Solutions of special coloring agents
For skin care products, lotions, ointments, shampoos, shower gels, deodorants, etc.

Hydrophilic actives:

DHA
Xylitol
Peptides
IS-DHA

St and Sc microcapsules

Obtained through a double encapsulation and formaldehyde-free technology patented at the beginning of 2015, these microcapsules are surfactant-resistant much like shampoo surfactants and other cleaning formulae. They are exclusively made for lipophilic ingredients.

MICROCAPSULES FOR THE TEXTILE INDUSTRY

Ever since it was created, MCT has produced melamine-based microcapsules containing perfumes and essential oils for the textile industry, as well as cationic gelatin-containing microcapsules for the needs of cosmetotextiles.
Substantial recent advances in encapsulation for the cosmetics industry have resulted in the development of functionalized silicone microcapsules (patent filed) specially suited to "cosmetotextiles" due to their perfect chemical compatibility with the skin.
Cationic microcapsules (SK) show superior affinity to textile fibers, allowing near 100% fixation rate and good wash resistance.
Binders are available to further increase this resistance for even higher requirements.
The IS and ISK forms allow fixation of aqueous actives to textiles.

With our partners in the cosmetics industry, we have developed a wide range of microcapsules for textile applications, that contain actives formulated for tights, panties, socks and underwear, with efficiency been proven by tests carried out according to strictly controlled protocols applied according to the accepted practice.

MICROCAPSULES FOR PAPERS AND NONWOVENS

This is the ideal field of action for our Company because of the knowledge it has acquired with self-copying paper.

Microcapsules are generally surface-deposited through coating or spraying. Once they are functionalized they develop strong affinity to paper fibers and therefore, can be incorporated within the paper or nonwoven batch. Based on these various techniques we can manufacture:

Scented, moisturising or decongestant tissue paper
Cleansing items (microcapsules activated by PH or humidity)
Security paper

GRAPHIC ARTS

The microcapsules produced by MCT can be deposited on paper, cardboard or plastic substrates through various printing techniques, such as:

Screen printing
Offset printing
Photogravure
Flexography

Generally employed in water-based inks, but formulas for UV and plastisol inks are available.

ODOR MASKERS AND DEODORANTS

A whole range of mechanically breakable or permeation microcapsules was developed for these uses.
Spray formulas are available for public and private areas.
8G microcapsules, which are entirely transparent and of the permeation type, are particularly attractive as they only require two applications per week for a permanent effect.

DETERGENCE

This has become a very important area of application, microcapsules are now ubiquitous in washing-powders, fabric-softeners and other detergents. By binding to the clothes, they reduce the consumption of perfumes and give the fabrics a pleasant and lasting fragrance.
At the beginning of 2015, MCT patented a complex silicon/organic encapsulation technology which lengthened surfactant lifespan.

Mt microcapsules have a very low formaldehyde content and are particularly suited to fabric softeners where they are widely used.

St microcapsules are completely formaldehyde-free. A recent market offering, they are also suited to liquid type detergents or powder detergents.

PHYTOSANITARY

Many specific industrial applications have been developed for infected countries, such as permeating and biodegradable gelatin-based microcapsules. Insecticides, repellents, disinfectants.

FOOD-GRADE PRODUCTS

MCT has developed a line of food-grade gelatin-based microcapsules ranging from 0.3 to 1.5 mm in diameter, that can be dried and offered as a colored or colorless flowing powder.
This line is mainly for encapsulating brittle or volatile ingredients, such as essential oils, highly unsaturated oils, aromas and food adjuncts.
